From THE MEANING OF MONEY by Ayn Rand

"Money is a tool of exchange, which can’t exist unless there are goods produced and men able to produce them. Money is the material shape of the principle that men who wish to deal with one another must deal by trade and give value for value. Money is not the tool of the moochers, who claim your product by tears, or of the looters, who take it from you by force. Money is made possible only by the men who produce. Is this what you consider evil?"

“When you accept money in payment for your effort, you do so only on the conviction that you will exchange it for the product of the effort of others. It is not the moochers or the looters who give value to money. Not an ocean of tears nor all the guns in the world can transform those Bitcoin in your wallet into the bread you will need to survive tomorrow. Those Bitcoin are a token of honor—your claim upon the energy of the men who produce. Your wallet is your statement of hope that somewhere in the world around you there are men who will not default on that moral principle which is the root of money. Is this what you consider evil?"

"Money is made—before it can be looted or mooched—made by the effort of every honest man, each to the extent of his ability. An honest man is one who knows that he can’t consume more than he has produced."

"To trade by means of money is the code of the men of good will. Money rests on the axiom that every man is the owner of his mind and his effort. Money allows no power to prescribe the value of your effort except the voluntary choice of the man who is willing to trade you his effort in return. Money permits you to obtain for your goods and your labor that which they are worth to the men who buy them, but no more. Money permits no deals except those to mutual benefit by the unforced judgment of the traders. Money demands of you the recognition that men must work for their own benefit, not for their own injury, for their gain, not their loss—the recognition that they are not beasts of burden, born to carry the weight of your misery—that you must offer them values, not wounds—that the common bond among men is not the exchange of suffering, but the exchange of goods. Money demands that you sell, not your weakness to men’s stupidity, but your talent to their reason; it demands that you buy, not the shoddiest they offer, but the best that your money can find. And when men live by trade—with reason, not force, as their final arbiter—it is the best product that wins, the best performance, the man of best judgment and highest ability—and the degree of a man’s productiveness is the degree of his reward. This is the code of existence whose tool and symbol is money. Is this what you consider evil?"

"Or did you say it’s the love of money that’s the root of all evil? To love a thing is to know and love its nature. To love money is to know and love the fact that money is the creation of the best power within you, and your passkey to trade your effort for the effort of the best among men. It’s the person who would sell his soul for a nickel, who is loudest in proclaiming his hatred of money—and he has good reason to hate it. The lovers of money are willing to work for it. They know they are able to deserve it. Let me give you a tip on a clue to men’s characters: the man who damns money has obtained it dishonorably; the man who respects it has earned it. Run for your life from any man who tells you that money is evil. That sentence is the leper’s bell of an approaching looter. So long as men live together on earth and need means to deal with one another—their only substitute, if they abandon money, is the muzzle of a gun."

"Society vanishes, in a spread of ruins and slaughter. Do you wish to know whether that day is coming? Watch money. Money is the barometer of a society’s virtue. When you see that trading is done, not by consent, but by compulsion—when you see that in order to produce, you need to obtain permission from men who produce nothing—when you see that money is flowing to those who deal, not in goods, but in favors—when you see that men get richer by graft and by pull than by work, and your laws don’t protect you against them, but protect them against you—when you see corruption being rewarded and honesty becoming a self-sacrifice—you may know that your society is doomed. Money is so noble a medium that it does not compete with guns and it does not make terms with brutality."

“Whenever destroyers appear among men, they start by destroying money, for money is men’s protection and the base of a moral existence. This kills all objective standards and delivers men into the arbitrary power of an arbitrary setter of values. Paper is a mortgage on wealth that does not exist, backed by a gun aimed at those who are expected to produce it. Paper is a check drawn by legal looters upon an account which is not theirs: upon the virtue of the victims."

“You stand in the midst of the greatest achievements of the greatest productive civilization and you wonder why it’s crumbling around you, while you’re damning its life-blood—money. You look upon money as the savages did before you, and you wonder why the jungle is creeping back to the edge of your cities."

“Until and unless you discover that money is the root of all good, you ask for your own destruction. When money ceases to be the tool by which men deal with one another, then men become the tools of men. Blood, whips and guns—or Bitcoin. Take your choice—there is no other—and your time is running out.”
